Environmental Effect of Hydroxyapatite Urea Application on Optimizing Urea Fertilizers for Wheat Plant

Managing Urea-Containing Fertilizers

Nitrogen fertilizer use in Wisconsin as anhydrous ammonia, urea-ammonium nitrate solutions, and urea ranged from about 148,000 to 213, 000 tons of N during the 19952000 period (Terry and Kirby, 2001). This amount is similar to that used about 10 years earlier when 170,000 tons of N was used in 1984. However, a substantial materials shift has occurred since 1984 when about 56% of the N used as t...

Effect of Feeding Dietary Treated Wheat Straw with Urea and Whey on Fattening Lambs Performance

This study was conducted to evaluate the effect of feeding treated wheat straw with urea and whey on fattening lambs performance. About 4.5 kg urea and 1.5 kg salt were dissolved in 40 L water and mixed with 30 L of whey. The solution was spread over 100 kg chopped wheat straw. Thirty two male lambs were randomly divided into four feeding groups to compare performance with diets based on barley...

Effect of urea foliar feeding on grain protein content and quality in two winter wheat cultivars

The effect of foliar application of urea, humic acid and micronutrients on potato crop

ABSTRACT- The influence of foliar application of urea, humic acid (HA), Zinc (Zn), and Boron (B) on potato yield (CV. Cror) was studied in a field experiment during 2010-2012 at the research farm of Nuclear Institute for Food and Agriculture (NIFA). Treatments consisted of i) Control, ii) Nitrogen-Phosphorous-potassium (NPK) (250,150,250 kg ha-1) , iii) NPK (125,75,125 kg ha-1) with 0.03% HA, i...
